Bunni DEX Suspends Operations After Hack Results in $8.4 Million Loss

A recent cybersecurity incident has prompted Bunni, a decentralized exchange utilizing Uniswap v4, to temporarily halt all smart contract activities. The breach is estimated to have drained approximately $8.4 million in cryptocurrency. According to blockchain security firm CertiK, the exploit targeted BunniHub, the primary contract system of Bunni, resulting in $2.3 million in losses on the Ethereum network. An earlier incident on Unichain, Uniswap Labs' layer-2 network, pushed the total losses to around $8.4 million. The stolen funds have been traced to two Ethereum wallets. In response to the incident, Bunni's developers have suspended all contract operations across supported networks while they conduct an investigation. In a social media post, the team stated, 'As a precautionary measure, we have paused all smart contract functions across all networks. Our team is actively investigating the incident and will provide updates soon. We appreciate your patience.' The exchange leverages Uniswap v4's 'hooks' feature, which, as described by Uniswap Labs CEO Hayden Adams, serves as 'plugins to customize how pools, swaps, fees, and LP positions interact.'
